Lower Electric Field-Driven Magnetic Phase Transition and Perfect Spin Filtering in Graphene Nanoribbons by Edge Functionalization

TL;DR: From the current-voltage characteristics of the edge-modified zGNR under an in-plane transverse electric field, a remarkable perfect spin filtering feature is found, which can be utilized for a molecular spintronic device.
Journal ArticleDOI

Electron Transport in Graphene Nanoribbon Field-Effect Transistor under Bias and Gate Voltages: Isochemical Potential Approach

TL;DR: The isochemical potential scheme to describe the top/ back-gate effect using external potential is presented and the change in electronic state under the modulation of chemical potential and the subsequent electron transport phenomena in zGNR transistor under substantial top-/back-gate and bias voltages is examined.
Journal ArticleDOI

σ to π conformational transition: Interactions of the water trimer with π systems

TL;DR: In this paper, the authors investigated the interaction of the water trimer with the aromatic π systems at the second-order Moller-Plesset level of theory using both the 6-31+G* and aug-cc-pVDZ basis sets.
Journal ArticleDOI

Non-adiabatic dynamics of ring opening in cyclohexa-1,3-diene described by an ensemble density-functional theory method

TL;DR: In this article, the dynamics of the ring opening in the S1 state of cyclohexa-1,3-diene (CHD) is studied by a new direct mixed quantum-classical non-adiabatic dynamics approach which employs the decoherence-induce.
Journal ArticleDOI

Structures, vibrational frequencies, and infrared spectra of the hexa-hydrated benzene clusters

TL;DR: In this article, the effects of benzene on the structures, harmonic vibrational frequencies, and infrared (IR) intensities for the four low-lying energy conformers, Ring, Book, Cage, and Prism structures, were investigated.
